With NYOS - Nitrate - 100ml, no more soaring nitrate levels that jeopardize the balance of your reef or freshwater tank. This product acts at the source: it stimulates the proliferation of beneficial bacteria that consume nitrates as a resource, biologically transforming them until they disappear. At the same time, a slight reduction in phosphates is also observed thanks to the natural elimination of biofilms.
Its dual-component formula combines immediate and long-term effects, making it a stable and sustainable solution over time. Whether you're looking to correct a one-time spike or maintain permanently low nitrate levels, this treatment adapts to your needs. It is completely safe for wildlife and flora , and contains no methanol.
The recommended dosage is 10 ml per 1,000 liters of water per day for standard maintenance. If the nitrate level is still too high, it is possible to temporarily double the dose to 20 ml/1,000 liters . Conversely, if the levels are close to ideal values, a reduced dose to 5 ml or a temporary stop may be sufficient. For accurate monitoring, it is advisable to perform a nitrate test every week , for example with the Nyos test, and adjust the dosage accordingly.
For greater consistency and simplicity, NYOS recommends the use of a daily dosing pump . The product is packaged here in a 1 L bottle, perfect for prolonged use even on large volumes.
By maintaining nitrates between 5 and 15 mg/l , you limit biological imbalances and reduce the risk of unwanted algae. This treatment is therefore particularly suitable for densely populated aquariums or reef tanks that require impeccable water stability . Thanks to its flexibility of use, it is suitable for both beginner aquarists and demanding enthusiasts.
